AllāhArabic “God”the AllahArabic Allāh (“God”)the one and only God in the religion of Islam. Etymologically, the name Allāh Allah is probably a contraction of the Arabic al-Ilāh, “the God.” The name’s origin can be traced back to the earliest Semitic writings in which the word for “god” was Ililor Elel, the latter being an used in the Hebrew Bible (Old Testamentsynonym for Yahweh). Allāh is the standard Arabic word for “God” God and is also used by Arab Christians as well as by Muslims.

Allāh Allah is the pivot of the Muslim faith. Islam’s holy scripture, the Qurʾān, constantly preaches Allāh’s Allah’s reality, his inaccessible mystery, his various names, and his actions on behalf of his creatures. Three themes preponderate: (1) Allāh Allah is the Creator, Judge, and Rewarder; (2) he is unique (wāḥidwāḥid) and inherently one (aḥadaḥad); and (3) he is omnipotent and all-merciful. Allāh Allah is the “Lord of the Worlds,” the Most High; “nothing is like unto him,” and this in itself is to the believer a request to adore Allāh Allah as the Protector and to glorify his powers of compassion and forgiveness.

AllāhAllah, says the Qurʾān, “loves those who do good,” and two passages in the Qurʾān express a mutual love between him and humanity, but the Judeo-Jewish and Christian precept to “love God with all thy heart” is nowhere formulated in Islam. The emphasis is rather on Allāh’s Allah’s inscrutable sovereignty, to which one must abandon oneself. In essence, the “surrender to Allāh” Allah” (islām) is the religion itself.

Muslim piety has collected, in the Qurʾān and in the Ḥadīth Hadith (the sayings of the Prophet Muhammad), the 99 “most beautiful names” (al-asmāʾ al-ḥusnāḥusnā) of AllāhAllah. These names have become objects of devoted recitation and meditation. Among the names of Allāh Allah are the One and Only, the Living One, the Subsisting (al-Ḥayy Ḥayy al-Qayyūm), the Real Truth (al-ḤaqqḤaqq), the Sublime (al-ʿAẓīmʿAẓīm), the Wise (al-ḤakīmḤakīm), the Omnipotent (al-ʿAzīz), the Hearer (al-Samīʿ), the Seer (al-Baṣīr), the Omniscient (al-ʿAlīm), the Witness (al-Shahīd), the Trustee (al-Wakīl), the Benefactor (al-Raḥmān), the Merciful (al-Raḥīm), and the Constant Forgiver (al-Ghafūr, al-Ghaffār).

At all times there have been freethinkers in Islam, but rare has been the Muslim thinker who has denied the very existence of AllāhAllah. Indeed, the profession of faith (shahādah) by which a person is introduced into the Muslim community consists of the affirmation that there is no god but Allāh Allah and that Muhammad is his prophet. For pious Muslims, every action is opened by an invocation of the divine name (basmalah). The formula inshāʾa Allāh, “if Allāh Allah wills,” appears frequently in daily speech. This formula is the reminder of an ever-present divine intervention in the order of the world and the actions of human beings. Muslims believe that nothing happens and nothing is performed unless it is by the will or commandment of AllāhAllah. The personal attitude of a Muslim believer, therefore, is a complete submission to AllāhAllah, “whom one does not question” but whom one knows according to his (Qurʾānic) word the Qurʾān to be a fair judge, at once formidable, benevolent, and the Supreme Help.
